Here comes the fix:

In the grammar file f2dep/cftn.gram, find the grammar rule "funcname",
and change one of its action statement

              $$ = make_function($1, TYNULL, LOCAL);
to
              $$ = make_function($1, TYNULL, YES);

Also, do the same thing to the grammar rule "typedfunc". 


This should eliminate the redundant function name symbol node. Please
let me know if there is any problem. Thanks!
